If the previews are any indication, it looks like Season 10, episode 5 of "The Real Housewives of Orange County" is going to be a real tear jerker. In a short clip released by Bravo, veteran housewife Vicki Gunvalson is handed some tragic news that just may change the dynamic of the entire season for her.

In the video the "RHOC" ladies are gathered for a relaxing game night at Shannon Beador's home. The get together is a refreshing change of pace from the last few episodes which have ended in shouting matches and tension. Unfortunately it didn't take long for things to go south. While the rest of the cast laughed, drank and played together, Vicki, who is generally the life of the party, appeared to be somewhere else mentally. The 53-year-old ducked into Shannon's craft room to make a quick phone call to her daughter Briana, at which time she learned of her mother's unexpected death.

She immediately dropped to the floor, crying and struggling to breathe. Through her tears she can be heard telling her daughter, "I don't want to believe this." On February 5, the night after she recieved the horrible news, Vicki took to Facebook to share with her fans what had happened. She wrote that her mother "died suddenly and unexpectedly in her home."

"The Real Housewives of Orange County" airs tonight at 9 p.m. EDT on Bravo. Check out a clip of the episode below:
